Description

Technical Field

[0001] This utility model relates to the field of pesticide granule processing technology, specifically to a mixer for pesticide granule processing that is easy to clean. Background Technology

[0002] Pesticides are chemical agents used in agriculture to control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry, and animal husbandry production, environmental and household sanitation pest control and disease prevention, and industrial products for mold and insect prevention. Pesticide granules are a solid dosage form obtained by mixing the active ingredient with carriers, binders, dispersants, wetting agents, stabilizers, and other adjuvants and granulating them. Their performance requirements mainly include fineness, uniformity, storage stability, hardness, and disintegration properties. They have the advantages of being easy to use, having minimal outward diffusion, and long-lasting efficacy.

[0003] In the processing of pesticide granules, the active ingredient and filler need to be mixed in a mixer to obtain a mixture. This mixture is then pulverized, stirred, and filtered by an air jet mill and cyclone separator before being transferred to a storage tank. It is then packaged by a dispensing machine, and the finished product is inspected and stored. The mixing drum of the mixer is often a one-piece structure. After multiple uses, the inside needs to be cleaned to remove impurities for reuse. Currently, a handheld cleaning gun is typically used to flush the inside of the mixing drum through the inlet. However, the cleaning effect is not ideal, leaving blind spots, especially at the bottom of the mixing blades (near the outlet), which cannot be effectively cleaned, affecting subsequent material processing. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a mixer for processing pesticide granules that is easy to clean. It includes a feeding cylinder 1 and a discharging cylinder 2 connected to the feeding cylinder 1. The feeding cylinder 1 and the discharging cylinder 2 form a mixing cylinder. The top and bottom of the mixing cylinder are respectively provided with an inlet and an outlet. The mixing cylinder is equipped with a stirrer. The active ingredient and filler are fed into the mixing cylinder through the inlet, and then the materials are stirred by the stirrer to form a mixture, which is finally discharged from the outlet. The bottom of the feeding cylinder 1 is provided with an upper interface 3, which matches the lower interface 4 located at the top of the discharging cylinder 2. The feeding cylinder 1 is connected to a drive mechanism for driving the discharging cylinder 2 to rise and fall. The upper feed cylinder 1 is connected to a positioning mechanism for positioning the lower feed cylinder 2. The positioning mechanism includes a motor 6, a rotating ring 5, multiple positioning blocks 15, and positioning bolts 14. The motor 6 is used to drive the rotating ring 5 to rotate. The rotating ring 5 is rotatably connected to the upper feed cylinder 1. Multiple positioning blocks 15 are connected to the rotating ring 5. Multiple positioning plates 16 are connected to the lower interface 4. The positioning blocks 15 are pressed against the positioning plates 16. The positioning bolts 14 are used to position the positioning plates 16.

[0023] There are usually three cylinders 11, with an included angle of 120° between adjacent cylinders. When the inside of the mixing cylinder needs to be cleaned, the three cylinders 11 synchronously drive the lower mounting base 13 to descend, which in turn moves the lower material cylinder 2 downward, making it easier to open the lower material cylinder 2 and facilitate cleaning of the inside of the upper material cylinder 1 and the lower material cylinder 2.

[0024] After cleaning is completed, the three cylinders 11 synchronously drive the lower mounting base 13 to move upward, which in turn drives the lower material cylinder 2 to move upward, so that the lower interface 4 and the upper interface 3 are connected. The positioning mechanism is used to position and lock the lower material cylinder 2, thereby improving the stability of the lower material cylinder 2.

[0025] Sealing surfaces 21 are provided at the bottom of the feeding cylinder 1 and the top of the feeding cylinder 2. The sealing surfaces 21 have an inclined structure. The two sealing surfaces 21 press against each other to improve the sealing performance of the connection between the feeding cylinder 1 and the feeding cylinder 2.

[0026] The drive mechanism includes multiple limiting heads 9, multiple guide columns 10, multiple cylinders 11, multiple upper mounting seats 12, and multiple lower mounting seats 13. The limiting heads 9 are connected to the ends of the guide columns 10. The upper mounting seats 12 are connected to the upper material cylinder 1, and the lower mounting seats 13 are connected to the lower material cylinder 2. The cylinders 11 are connected to the upper mounting seats 12, and the power output end of the cylinders 11 is connected to the lower mounting seats 13. The guide columns 10 guide the lower material cylinder 2. When the lower material cylinder 2 is raised or lowered, it synchronously drives the guide columns 10 to move, i.e., the guide columns 10 slide relative to the upper mounting seats 12, improving the stability of the lower material cylinder 2's raising and lowering, and facilitating the precise passage of the positioning plate 16 through the rectangular hole 17. When the lower material cylinder 2 is fully open, the limiting heads 9 are connected to the upper mounting seats 12. At this time, the cylinders 11 are in a stopped state, and the limiting heads 9 can support the lower material cylinder 2, facilitating subsequent flushing operations.

[0027] The bottom of the guide post 10 is connected to the lower mounting base 13, and the guide post 10 is slidably connected to the upper mounting base 12.

[0028] The positioning mechanism also includes a gear 7, teeth 8, and multiple inclined grooves 18. Teeth 8 are located on the rotating ring 5 and are matched with gear 7. A motor 6 is fixed to the outside of the upper feed cylinder 1, and the power output end of the motor 6 is connected to gear 7. Inclined grooves 18 are located on the positioning plate 16, and positioning blocks 15 are pressed against the inclined grooves 18. There are six positioning blocks 15, with adjacent blocks having an included angle of 60°. When the lower interface 4 and the upper interface 3 are connected, the motor 6 drives the gear 7 to rotate. The gear 7 and teeth 8 cooperate to drive the rotating ring 5 to rotate, thereby achieving synchronous rotation of the six positioning blocks 15. This causes the positioning blocks 15 to press against the positioning grooves 22 of the positioning plate 16, achieving limiting and fixing of the positioning plate 16 and applying an upward pushing force to it. Combined with the use of the sealing surface 21, this improves the stability and sealing of the connection between the lower feed cylinder 2 and the upper feed cylinder 1, preventing material leakage.

[0029] Gear 7 meshes with tooth 8, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio.

[0030] A T-shaped groove 20 is provided on the outer side of the feeding cylinder 1. Multiple sliders 19 are slidably connected to the T-shaped groove 20, and the sliders 19 are connected to the rotating ring 5. When the rotating ring 5 rotates, it drives the sliders 19 to slide within the T-shaped groove 20, thereby improving the stability of the rotation of the rotating ring 5 and ensuring the transmission effect between the rotating ring 5 and the gear 7.

[0031] The upper interface 3 is provided with a rectangular hole 17, the bottom of the positioning plate 16 is connected to the lower interface 4, and the positioning plate 16 is slidably connected to the rectangular hole 17.

[0032] The positioning bolt 14 is threaded to the upper interface 3. The side of the positioning plate 16 is provided with a positioning groove 22, and the end of the positioning bolt 14 matches the positioning groove 22. When the positioning block 15 is pressed against the positioning plate 16, the positioning bolt 14 is rotated so that its end connects with the positioning groove 22 of the positioning plate 16, which improves the stability of the connection between the upper interface 3 and the lower interface 4. At this time, the motor 6 is in the stopped state.

[0033] There are usually three positioning bolts 14, with an adjacent included angle of 120°, meaning that the positioning plate 16 in the middle of the three positioning plates 16 is not locked by the positioning bolts 14.

[0034] Working principle: When the inside of the mixing cylinder needs cleaning, three cylinders 11 drive three lower mounting seats 13 to descend synchronously, causing the lower cylinder 2 to descend. The guide column 10 slides relative to the upper mounting seat 12, guiding the lifting and lowering of the lower cylinder 2. When the limit head 9 connects with the upper mounting seat 12, the mixing cylinder is fully opened, and the distance between the upper cylinder 1 and the lower cylinder 2 is large, providing sufficient operating space for cleaning the internal structure. After cleaning, the cylinders 11 drive the lower cylinder 2 to move upward, the positioning plate 16 passes through the rectangular hole 17, and the lower interface 4 connects with the upper interface 3. The motor 6 drives the gear 7 to rotate, and the gear 7 engages with the teeth 8 to rotate the rotating ring 5, which in turn drives the six positioning blocks 15 to rotate, pressing the positioning blocks 15 against the inclined groove 18 of the positioning plate 16, applying an upward pulling force to the positioning plate 16, pressing the lower interface 4 against the upper interface 3. Combined with the use of the sealing surface 21, the stability and sealing of the connection between the upper cylinder 1 and the lower cylinder 2 are improved. Finally, operate the three positioning bolts 14 to connect their ends to the positioning grooves 22 on the side of the positioning plate 16, thereby limiting and fixing the positioning plate 16, and stopping the motor 6.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
